A botched inquiry into British intelligence misconduct uncovers a deadly Cold War operation in 1994 Berlin—and reveals the secret origins of Jackson Lamb.
Spanning nearly thirteen breathtaking, immersive hours, *The Secret Hours* is Mick Herron’s standalone masterpiece set within the Slough House universe—a thrilling, poignant companion novel that illuminates the shadowy Cold War origins of the series' most iconic spymaster. The story begins in contemporary London with the 'Monochrome Inquiry,' a toothless, underfunded government commission established by an ambitious Prime Minister to investigate historical wrongdoing within the British intelligence services. Led by cynical civil servant Griselda Fleet and bumbling lawyer Malcolm Kyle, the inquiry has spent two years filing boring reports without uncovering a shred of evidence.
That is, until an anonymous dossier arrives detailing an unsanctioned, catastrophic black operation conducted in post-unification Berlin in 1994. Suddenly, the inquiry becomes dangerously relevant. As an elite MI5 hit team attempts to eliminate witnesses across the British countryside, the narrative leaps back to Berlin in the chaotic years immediately following the fall of the Wall. There, in a city teeming with former Stasi agents, CIA operatives, and ruthless Russian mafiosi, a young, idealistic British operative code-named 'Max' runs an unsanctioned network—and triggers a devastating betrayal whose repercussions echo through decades.
For longtime fans of the Slough House series, *The Secret Hours* provides the definitive, long-awaited revelations regarding Jackson Lamb’s past, the tragic history of David Cartwright, and the true origins of the 'slow horses' program. Herron seamlessly combines the nostalgic, smoke-filled atmosphere of classic John le Carré mole-hunts like The Spy Who Came in from the Cold with his signature modern cynicism and mordant wit. Narrator Sean Barrett delivers an extraordinary, emotionally resonant performance that elevates this 12-hour epic into one of the greatest spy audiobooks of the decade.
